An array substrate includes a plurality of driving units, where each of the plurality of driving units includes a first electrode, a second electrode and at least one thin film transistor; the first electrode and the second electrode are configured to be connected to an anode and a cathode of a light-emitting diode, respectively, such that a vertical projection of the light-emitting diode on the array substrate overlaps with the at least one thin film transistor, and in a light-emitting direction of the light-emitting diode, the at least one thin film transistor is disposed on a backlight side of the light-emitting diode; and each of the plurality of driving units controls the light-emitting diode to be turned on or off according to a driving signal.
